Inaugural lecture focuses on understanding society
Dr Kristina Riedel, Head of the UFS Department of Linguistics and Language Practice with Prof Kobus Marais at his inaugural lecture in May.
Understanding what the terms ‘social’ and ‘cultural’ mean and where they come from is important for Prof Kobus Marais. “If one thinks about it carefully, there was a time in the history of the universe and Earth that terms like ‘social’ and ‘cultural’ did not exist. So, if they did not exist from the very beginning, they must have emerged through some process,” he said at his inaugural lecture held earlier this year.

Prof Marais is a senior lecturer in the Department of Linguistics and Language Practice at the University of the Free State (UFS). His interest is in translation studies, but he is conceptualising translation as a technical term that refers to the semiotic process   in other words, the process through which living organisms create meaningful responses to an environment. 

Semiotics entails the study of signs, and it holds that anything in the universe can act as a sign or be interpreted as one. “A tune can be a sign of resistance against political domination, such as Give me hope, Jo’anna, a song by Eddie Grant, and smoke can be a sign of fire, just as the word ‘rose’ could be a sign of a sweet-smelling flower of any colour,” Prof Marais said. 

The universe is perfused by signs, and we are constantly interpreting them, from traffic signs to buildings to agricultural practices to more abstract things like ‘the law’, ‘politics’, ‘economics’ or ‘religion’. All of these things mean something to us and were made as meaningful responses to an environment.

Inaugural lectures vital part of any university
“Inaugural lectures afford professors the opportunity to table a broader research agenda as well as the opportunity to reflect on meta-disciplinary concerns,” Prof Marais said.

He said during the lecture, he had worked out “a theory of translation that explains some aspects of where social/cultural things come from and how they come to be”. An idea that society, and or culture, are a result of translation processes, that is, “processes in which organisms (human beings in this case) respond to an environment in a meaningful way by creating social relationships and cultural phenomena”. 
“Social and cultural phenomena thus all have a meaningful (semiotic) dimension or aspect that I would like to study,” he said.

UFS research could light up South African homes
2016-01-21

Reitumetse Maloa, postgraduate student and researcher at the UFS Department of Microbial, Biochemical and Food Biotechnology, is using her research to provide solutions to the energy crises in South Africa.

A young researcher at the university is searching for the solution to South Africa’s energy and electricity problems from a rather unlikely source: cow dung.

“Cow dung could help us power South Africa,” explains Reitumetse Maloa, postgraduate student and researcher at the UFS Department of Microbial, Biochemical and Food Biotechnology.

Reitumetse’s research is trying to understand how the bacteria works that is responsible for producing biogas.

“Biogas can be used for cooking, heating, lighting and powering generators and turbines to make electricity. The remaining liquid effluent can fertilise crops, as it is high in nitrogen, phosphorus and potassium.”

By using cow dung and food waste to produce biogas, we will be able to lower greenhouse gases.

Biogas is produced in a digester - an oxygen-free space in which bacteria break down or digest organic material fed into the system. This process naturally produces biogas, which is mainly a mixture of methane and carbon dioxide.

“Many countries, such as Germany and the United States, have begun generating electricity from cow dung and food waste, through a process known as biogas production. In South Africa, a number of industries, including waste-water treatment facilities and farms, have caught on to this technology, using it to generate heat and to power machines.”

Until recently the world has relied heavily on electricity derived from fossil fuels such as coal, natural gas and oil. Once these fuels have been extracted from underground reservoirs, they are treated or cleaned, transported to power plants and transformed into the electricity that will reach your house. Fossil fuels are considered a ‘dirty’ energy source which gives off greenhouse gases when burned. Those gases are the major contributing factor to climate change.

“We know very little about the interaction of the bacteria inside the biogas digester. To use biogas as a sustainable fuel source, we need to understand and describe the bacteria population and growth dynamics inside the digester to produce biogas optimally. Currently we are testing a variety of feedstock, including bran, maize and molasses, for biogas production potential, as well as optimising the conditions leading to maximum biogas production. We are also exploring the potential to use the effluent as fertiliser on local farms. The ultimate goal is to have biogas systems that will supply our university with clean energy.”
